+# CLAUDE.md
+
+This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
+
+## Project Overview
+
+This is the Atomic Transact JavaScript SDK, a browser-based SDK that enables integration with Atomic's financial services through an iframe-based widget. The SDK provides a simple API to launch the Transact experience and handle callbacks for user interactions.
+
+## Development Commands
+
+- **Test**: `npm test` or `jest` - Runs Jest test suite
+- **Build TypeScript definitions**: `npx tsc` - Generates TypeScript declaration files from JavaScript source
+- **Publish**: `npm run publish-it` - Compiles TypeScript definitions and publishes to npm
+
+## Architecture
+
+### Core Structure
+- **index.js**: Main SDK implementation - single file containing the complete SDK
+- **index.d.ts**: TypeScript definitions (auto-generated from index.js via JSDoc comments)
+- **test/index.spec.js**: Jest test suite with snapshots
+
+### SDK Architecture
+The SDK follows a simple pattern:
+1. **atomicSDK.transact()**: Main entry point that creates an iframe and handles configuration
+2. **_handleIFrameEvent()**: PostMessage event handler for iframe communication
+3. **_removeTransact()**: Cleanup function for removing iframe and event listeners
+
+### Key Components
+- **iframe Management**: Creates and styles iframe elements, supports both modal and container modes
+- **PostMessage Communication**: Bidirectional communication with Transact iframe using postMessage API
+- **Event Callbacks**: onInteraction, onDataRequest, onFinish, onClose callbacks for different SDK events
+- **Product Constants**: Predefined product types (DEPOSIT, VERIFY, IDENTIFY, WITHHOLD)
+
+### Configuration
+- **Origin Override**: `environmentOverride` parameter allows pointing to different Transact environments
+- **Platform Metadata**: SDK automatically includes platform information (browser, SDK version, system details)
+- **Container Support**: Can render as modal overlay or embedded in specific DOM container
+
+## Code Style
+
+- Uses Prettier with specific config: no semicolons, single quotes, 2-space tabs, no trailing commas
+- TypeScript definitions generated from JSDoc comments in JavaScript source
+- Jest for testing with snapshot testing for DOM elements
+
+## SDK Version Management
+
+The SDK version is hardcoded in index.js:52 and should be kept in sync with package.json version. This version is sent to Transact servers as part of platform metadata.
